The wait for cash pledged to more than 6,500 former Longbridge workers nearly seven years ago is set to drag on.

A preliminary hearing to decide whether MG Rover parent group Phoenix Venture Holdings can pursue its legal fight against banking giant HBoS was concluded on Wednesday without a ruling from the High Court.

The case concerns £12 million pledged to car workers by Phoenix chairman John Towers following the closure of MG Rover amid debts of more than £1 billion in April 2005.

The case went before a High Court Registrar in the Chancery Division of the High Court when lawyers for Phoenix Venture Holdings argued for the disclosure of financial information related to the assets of MG Rover, which passed between administrators PwC and HBoS in 2005.

After an all-day hearing, the judgment was reserved.

An announcement is now expected over the next few weeks.

The outcome of the London hearing remains key to the long-held hopes of cash payouts by more than 6,500 ex-MG Rover workers.
